The tubular plastic parison obtained by extrusion or injection molding of thermoplastic resin is heated (or heated to a softened state), placed in a split mold, and compressed air is introduced into the parison immediately after closing the mold to blow the plastic parison It is inflated and adhered to the inner wall of the mold, and is cooled and released to obtain various hollow products.

Under normal circumstances, the regular maintenance of the blow molding machine equipment is once a year, and the time is often arranged during the first few days of the holiday break or during the holidays. The equipment management personnel participate in the guidance work, and the equipment maintenance workers and operators cooperate. jobs. The main contents of the regular maintenance work on the equipment are as follows:

Inflation is a topic that Chinese people have been paying attention to recently. Under the influence of various economic factors, China's CPI index has increased year by year. The rising sales prices of various products in the market have also brought a series of cost pressures to business owners.

Through the practice of automatic blow molding machines for many years, we also feel that imported blow molding machines, especially large blow molding machines, are not perfect, and there are also many problems and defects. Through our study and deepening of the blowing machine, we can find out where the problem lies, and boldly improve some problems and achieve better results.

The outstanding points of the blow molding machine test machine have the following four aspects: First, the lack of cooperation tacit

Extrusion blow molding machines, also known as hollow blow molding, are a rapidly evolving plastic processing method. The tubular plastic parison obtained by extrusion or injection molding of the thermoplastic resin is placed in a split mold after being heated,

The numerical control machining of the blowing mold has a certain typicality and has higher requirements than the numerical control processing of ordinary products. In the processing of molds, various CNC machining are used. The most widely used CNC milling and machining centers. The application of CNC wire cutting and CNC EDM in CNC machining is also very common. Wire cutting is mainly used in various Straight wall mold processing, such as concave and convex molds in press processing, inserts, sliders in blow molds, electrodes for electrical discharge machining, and the like.

Plastic PVC is also a general-purpose plastic for blow molding machinery with good induction function and low price, and it has many additives. It can adjust the formula, and the large undulation also changes the function of the product, for example, it can be added less or not. A plasticizer is added to produce a rigid plastic

1 The bottle of the automatic blow molding machine cannot be taken out of the mold after being blown. Firstly, the mold should be opened, and the mold should be opened and closed manually. If it is normal, run it in the air condition, if it is normal.

Blow molding machines can be divided into three categories: extrusion blow molding machine, injection blow molding machine and special structure blow molding machine. Stretch blow molding machines can be assigned to each of the above categories.
